Diving in warm water lets us pare down our gear to the bare necessities. Here’s some lightweight, comfortable gear for the job.

MARES ULTRASKIN STEAMER

Warm water means thinner wetsuits with less buoyancy, which means diving with less weight. But this suit takes it step further with zero buoyancy, thanks to its advanced, three-layer fabric. The inner layer is soft, insulating fleece, with a breathable inner membrane and a high-stretch outer layer. A long front zipper makes it easy to don and doff, and foot stirrups and thumb loops keep it place if you pull another suit over it.

SCUBAPRO GO TRAVEL FIN

Aimed at travelers, these lightweight kickers are designed to be worn barefoot, making them ideal for conditions where you don’t need the insulation or protection of a boot. The contoured foot pocket and supple bungee strap offer a stable, comfortable fit. Though just 20 ¼ inches long in size medium-large, the fin delivers a surprising amount of power, with its wide blade set at a steep 25-degree angle to the foot pocket, and supported by deep ridges and side rails.

CRESSI LIGHTWING

Weighing less than 5 pounds, with a harness you barely notice when diving, the Lightwing lets you do without extra weight and bulk. A flexible backplate and special air-net padding in the shoulders and back adds comfort and reduces water retention. The curved should straps contour to your body and provide an open and airy feel. There are enough D-rings and web loops, plus a drop-down cargo pocket, for the essentials. The integrated weights are a snap to load and ditch easily, and a pair of supports built into the lower back prevents tank and adds stability.

HOLLIS MESH DUFFLE BAG

Both and the top and the bottom of this duffle are made of coated mesh, so it drains quick and helps air out wet gear—helping to keep at bay the funkiness that come with letting your wet gear stew in the heat. The sides are constructed of heavy-duty coated fabric, with stout nylon handgrips sewn on each end. It also has top carrying handles and an adjustable shoulder strap, giving lots of places for your hang onto. At 25x14x13 inches it’s got room for your full warm-water kit, and it’s easy to load and unload through the generous, U-shaped top zipper. There’s also an almost-hidden zippered pocket on the inside at one end for small items.

AKONA TANAMI SLING DRY BACKPACK

Measuring 23 inches tall and 12 inches wide, it’s big enough to give dry protection for a full set of clothes and other belongings. Side mesh pockets are sized for water bottles, and an adjustable bungee and web loops offer places to secure towels or damp gear. The shoulder sling makes for easy carrying, and can be detached when you don’t need it.

TUSA M1007S PARAGON S

The frame of the Paragon S has an internal metal crossbeam sandwiched between polycarbonate and a polyurethane exterior for a strong but very lightweight design. The large single lens of the Paragon S offers a wide-open view, and the UV 420 coating blocks harmful ultraviolet rays. The supple silicone skirt is designed for a comfortable, leak-free seal, with alternating dimpled and reinforced areas to shape it to your face. The split strap has angled adjustors with five adjustment points to keep the mask exactly where you want it.

Wireless air integration puts your tank data on your wrist, and onboard Bluetooth lets you wirelessly download and share your dives via the free Diverlog+ app. Intuitive menus and a four-button interface make it quick to setup and program, and the high-contrast screen is easy to read whether at depth or on the surface. To grab your attention for critical data, it has programmable audible alarms, including an optional deep stop, and a high-visibility LED warning light. It pairs with up to three transmitters and is powered by a user-replaceable battery.

IST SPORTS FREEDIVING BOAT SOCKS

Designed for use with freediving fins, they’ll work as a liner inside any barefoot fins to prevent chafing or rubbing, as well as providing some insulation.
